Refrigerator recycling

A professional recycling system must include a four-stage process: Pre-treatment (removal of compressors and oils), Crushing/Shredding (heavy-duty twin-shaft shredders), Sorting (magnetic separators for ferrous metals and eddy current separators for non-ferrous metals), and Dust Collection. Ensure the system features PLC automated control for operational safety and efficiency.

The most critical factor is the CFC/Pentane recovery system. High-end equipment must feature a closed-loop suction system and activated carbon adsorption or cryogenic condensation units to capture blowing agents from the polyurethane (PU) foam. Verify that the machinery complies with ISO 14001 environmental standards and local emission regulations to avoid legal penalties.

Evaluate the purity rate of output materials; top-tier machines achieve >95% purity for iron, copper, and aluminum. Additionally, check the PU foam density and moisture content after separation. The processing capacity should be rated in units per hour (e.g., 30-80 units/h), and the equipment should be capable of 24/7 continuous operation with minimal downtime.

The shredder blades are the primary wear parts. Ensure they are made of high-alloy steel (such as D2 or SKD-11) with a hardness of HRC 58-60. Ask the supplier about the blade replacement cycle and whether they provide a self-sharpening mechanism or easy-access maintenance hatches to reduce labor costs.

Due to the size, these lines are shipped in multiple 40HQ containers. You must negotiate Incoterms like CIF or DDP clearly. Ensure the contract includes on-site installation guidance and commissioning services. It is highly recommended to use Made-in-China.com's secured payment services to hold the final 10-20% of the payment until the machine is successfully running in your facility.

The biggest risk is specification mismatch. Mitigate this by requesting a FAT (Factory Acceptance Test) via live video or a third-party inspection agency like SGS or Intertek before balance payment. Ensure the supplier provides a comprehensive English manual and remote technical support via AR or video conferencing to resolve potential operational issues quickly.

Focus on suppliers with 'Audited Supplier' status on Made-in-China.com. Check their export history to your specific region, as they will be more familiar with your local voltage requirements (e.g., 480V/60Hz vs 380V/50Hz) and safety certifications like CE or UL. A supplier with more than 10 years of manufacturing experience in the recycling sector is preferred.
